IMPROVING ON THE BEST

The restomod industry has boomed over the past 10 years, with many following the same template. Tuthill's 993 RSK, though, is different, and could well be our favourite concept. Total 911 brings you the inside line on its creation...

Tuthill Porsche is arguably one of the most respected Porsche specialists in the UK. The company has vast experience in terms of air-cooled Porsche, especially when it comes to building rally cars, engine enhancement, restorations and other development work.

Two years ago Tuthill launched its sensational 911K. This was a beautifully simplistic, air-cooled 911 that tips the scales at less than 900kg and revs to 11,000rpm. Needless to say, much development and engineering expertise went into the engine and the special 24-valve head that made these high engine speeds possible. Fast-forward to 2024, and one of its latest products, the 993 RSK, has again attracted serious interest from enthusiasts.

Purchasing an already fantastic 911 in the form of the 993 Carrera RS, one client was longing for a little more in terms of performance. After some indepth discussions, the idea of a complete restomod was pushed to one side. Instead, small improvements on every level would be made during the build process of the Tuthill RSK.

One of the most significant upgrades becomes obvious when you look at the tilted rev counter, with a redline that now starts at a lofty 8,000rpm. If the green exterior appeals to you, then you have Ferrari to thank: the colour is called Verde Francesca, while that flying pink pig is painted on, and not merely a sticker. Richard Tuthill explained to us in detail the elements of this project and the overall aim.

“A friend of mine, who is also a client, is the owner of a 911K. He was my partner in crime in creating that original gold-coloured car. One of the great ideas from the 911K was that we could use the top end on bigger engines like that from the 964 and 993 to create four-valve [per cylinder], higher-revving engines in larger capacities. I always said that the 993 Carrera RS, if not the best 911 Porsche ever made, is one of the best – but this is my opinion.
